The object of my invention is to make a substantial and. comparativelycheap hand platform truck which will withstand *the rough usage to whichsuch a truck is subjected.

Referring particularlyto igs. 1 to 4 inclusive, the platform 1 ispreferably made 56 from a single sheet of metal. 'Ihe` blank is Fig. 18,the side member of HAND TRUcx 1927. serial No. 182,373.

formed and cut at the corners as shown in F1g. 3. The edges of the blankare bent on the line a' to form a narrow reinforcing flange `2, andthenbent on the line y to form the sides 3 and ends 4 of the platform asshown in Fig. 4. The sides 3 and ends 4 are preferably welded at thecorners, making a very substantial platform. In large trucks, theplatform may be reinforced by one or more cross-barswelded or otherwisesecured to the. platform.

As shown in Figs. 3 and v5, the ends and sides Aof the platform may havea number'of perforations at the corners, so that dierent types of stakepockets may be secured theret'o. Thus the platforms may be made inquantities and held in stockLthe fittings being applied as orders arereceived.

The axle 5 of the truck ismounted in bearings 6-6 depending from theunderside of the platform. Each bearing is made in two parts, a bodyportion 7 and a journal box 8. The body portion 7 is bent to form ianges9 at each side, and the lower end hasa curved 'recess therein to receivethe cylindrical journal box 8, which iswelded thereto at fw and w. Thebody portion of each bearing 6 is welded to the platform at fw and tothe inturned flange at u.

Mounted on the axle are wheels 10. The axle 5 is held from rotating inthe bearings by bolts 11, leaving the wheels 10 free to turn on the axlein the present instance, but in some instances the axle may turn in thebearing. i

Brace plates 12 are securedto the underside of the platform near ach endas lshown in Fig. 2. Each plate is bent as shown in Figs. 6 and 7 toform a liat bearing portion 13, a vertical portion 13a, and an inclinedportion 13".

A wear' plate or race plate 14 (when ballbearings are used) is securedto the bearing portion 13 as shown in Fig.. C. The inclined portion 13bis securedtol the body of the platform by welding as at t, and theverticaly portion 13a is secured to the body of the platform at s and tothe inturned flange of the platform at p. The plate is made wide toaccommodate the wear plates of the caster 16 and also 1U' strains towhich the caster is subjected. ach caster has a wheel 17 mounted on aspindle carried by a forked portion 18. y The spindle 19 of the casterpro- ]ects through an opening in the bearing late and in the plate 12.If a 'ball-bearing 1s used, then the bearing plateof the caster is inthe form of a raceway and balls'are located between the two raceways asshown in to resist an y theiabove construction, the casters and theirbearings will withstand considerable rough usage, as the plate 12resists any pressure exerted on the caster and its parts.

At the corners of the platform are stake pockets 20, shown in Figs. 11and 12. These pockets have rectangular openings in the present Ainstance to fit correspondingly shaped stakes 21. Each pocket is madefrom a met-al plate cut and bent to form the pocket portion 22 and twoextensions 23 and 24. The extension 24 is longer than the extension 23and is bent as at 25. A back plate 26 closes the open side of the pocketand is Welded to j the extension 23, ,or the plate may 'be welded orsecured to the extension 24 by a rivet 27.

Elongated bolt holes 28 are formed in the two extensions to receive thebolts 29 which extend through certain of the perforations at the cornersof the platform.

The socket in Fig. 12, an the plate 26 has an inturned flange 30 whichacts as 'a stop for the end of the'stake 21.

The stake pockets may be made as shown in Fig. 13. l shapedsubstantially as shown in F1gs. 9 and 10, and the plate 26b may be aflat plate welded to the plate 20b at fv--QL The axle bearing` may bemade as shown 1n Fi 14. In this instance the journal box 8L 1s ahalf-box welded to the part 7, and a cap plate 8" when used is securedin place by the bolt 11". In some instances the cap plate may beomitted.

In Fig. 15 is shown a modification of the bearing, in which a piece ofmetal is shaped to form a half-bearing 8, and has extensions 8'l whichare secured to the flanges 9 of the body 7 of the bearing.

In each of Figs. 16 and 17 a modification of the bearing for the axle isshown, the bearing 6'* being U- haped and welded to the body of theplatform at m and to the lnturned flange at n. The axle 5a is short asshown 1n Fig. 17. f

When an end rack is used, as in Figs. 18 and 19, side members 31,angular in cross-section as in Fig. 20, are connected to the platform byknee-plates 32, which are securely attached to the platform and to theside members of the rack by bolts or other fastening means.

The upper ends of the side members are bent outward, and a hollow handlebar 33 is (portion is extended vas shown'v In this instance the plate2Ob is attached to the ends of the side members by rivets which passthrough one of the angle ,flanges of each side member and through thethe cross-pieces for the same purpose.

In-Fig. 18 the main axle 5x1 is at one end of the truck, and two swivelcasters 16a are located at the rack end of the truck. Each caster ismounted under a late 12b which extends to the underside of t 1e platformand is welded thereto.

In Figs. 21 and 22 are shown modifications of the casters.

Secured to each end of the platform are brace plates 12, bent as shownin Fig. 7 so as to form a rearwardly extending strut 13 which is weldedor otherwise secured to the underside of the platform. The verticalportion v13d extendsbetween a vertical spindle bearing 14 and the end ofthe platform, bolts securely holding the bearing to the'brace plate andplatform. Each caster 16a has a wheel 17a mounted on a spindle carriedby the forked portion 18EL of the caster, and projecting from the forkedportion is a spindle 19a mount-ed in the bearing 14'\.

I claim 1. The combination in a platform truck, of a body portion bentat each end to form deep flanges; bearing plates under the platform,each plate having a horizontal portion, a vertical portion, and aninclined strut portion, said vertical portion being welded to theunderside of the body of the latform and to the flange thereof, and theinclined portion being also welded to the underside of the body of theplatform; and a caster mounted under the bearing. plate.

2. The combination in a platform truck, of a body portion bent at theends to form deep inturned flanges; bearing plates under the platform,each plate having a horizontal portion, a vertical portion, and aninclined strut portion, the vertical portion and the inclined strutportion being welded to the underside of the body of the truck, and thevertical portion being also welded to the inturned flange of theplatform; a wear plate secured to the horizontal portion of thebearing'plate; and alcaster pivotally mounted under the bearing p ate.

3. The combination in a platform truck, of a platform having a deepinturned flange; an axle; wheels; and bearings for the axle welded tothe underside of the platform and to the inturned portion of the flange.

4. The combination in a platform truck, of a platform having a deepinturned flange; and a wheel-bearing, said bearing being welded to theunderside of the platform and to fiinhe intured edge of the age ofsaid^-p1at l orm. v

v, 5. The combination .in a platform trllek,V of a platform' having deepsideanges; anP axle; Wheels on the axle; bearings for the axle extendin-`to the under-side of the plat' .ormand wel ed thereto and to the deepside flanges thereof, the body portion of each bearing having laterallanges and recessed at its -lower'end betweenA the anges; and a journalbox mounted in the recess and s 'e I cured to said bearing. f A
